求解释这两个短语的区别

大体意思都是六个月的训练,但强调点不同.
six months of training 强调训练时间,比如：He learned a lot after six months of training.
the training of six months 强调训练类型,比如 The training of six months will cost 3500 dollars.
你可以从直译角度理解这两者的差别.six months of training 是 “以训练为内容的六个月”；而 the training of six months 则是 “六个月长短的训练”.
